NOVELTY BY GENOME EDITING. “After a duplication, when a copy is usually released from selective pressure, there might be rapid changes that either lead to gene inactivation or, in rarer cases, exaptation into a new or variant function. However, this concept does not explain generative competences for evolutionary novelty in terms of genome editing.” There is no evolution without infection.
